Ran out of Ink
Style: Ink
This product prints a lot of black & white, as well as color. Our business requires a lot of ink for our Epson.

Reliable, Long-Lasting Ink for Crisp Prints!
Style: Ink
The Epson 812 XL ink works perfectly with my Epson WF-7840! The colors are vibrant, and the black is deep and sharp. Every print comes out crisp and professional looking. The XL size lasts a long time, which means fewer replacements and better value. Installation was quick and easy, and the printer recognized it immediately with no issues. I’ve been using it for documents, photos, and labels, and it performs consistently every time. A must have for anyone who wants high quality prints without frequent refills!

When a single one cartridge in a set fails :(
Style: Ink, Style: Ink
This for use in my oldish Epson WF-7840 model, which is an ink guzzler; its decent print quality and large paper format notwithstanding. For work projects and good color on laser & gloss papers, this is the only good ink choice on this model. Well, that is, IF you get all ink cartridges in a set working.
Therefore, given its price, it is frustrating that, when a brand new single cartridge (of a set) fails, you can be left with few good choices. Along the years, this has happened to me twice...plus today, just one, of a pricey Epson set, failed. When I've bought from a local store, they have had no problem helping with this issue in the past.. I am sure that Amazon & Epson will make it right also.
YET, I do have to send back the whole set, even for a single cartridge replacement, which they DO HAVE AS A SEPARATE item. It is a bit of a drag because I need the printer working now and this magenta ink cartridge is all I needed to work at this time.
How about dedicating some of Amazon's awesome IT & AI power to distinguish and better respond to this kind of situation? After all, Artificial Intelligence can sort this kind of thing in just a bit or two.
